BADAS 2.0
The world's best incident prediction model, period.
BADAS 2.0 is a world model that has internalized physics and causality. Wetrained it on 2M real-world driving clips. We fine-tuned NVIDIA's Cosmos on thesame data. BADAS wins – at 91x fewer parameters. We publish everything. Try ityourself.

0.994 AP vs 0.940. Same Data. Different Architecture.
We fine-tuned NVIDIA's Cosmos-Reason2-2B on the exact same 2M training clips. BADAS 2.0 achieves 99.4% AP. Cosmos achieves 94.0%. At 91x fewer parameters, our smallest model still beats their largest. We publish our benchmarks and invite direct comparison.

The Work Zone Crisis
Every year, U.S. work zones claim nearly 900 lives, strip cities of over a billion dollars in unpaid fines, and add half a billion hours of congestion to American roads. The root cause is always the same: no one knows what’s actually happening out there.
NYC DOT processes 700,000 street construction permits a year, but a State Comptroller audit found nearly 300,000 received no inspection at all. 150 field inspectors. 6,000+ miles of streets. Every un-inspected permit is a compliance gap, a safety risk, and an uncollected fee hiding in plain sight

Real-time road intelligence. Updated daily by the vehicles already driving your streets.
CityStream Work Zones uses Nexar’s nationwide fleet of 350,000+ AI-powered dashcams to continuously detect, classify, and monitor road work zones — at city scale, at state scale, across the entire U.S. main road network.

No survey trucks. No drones. No field visits required. Ground-truth intelligence, delivered continuously.

How It Works
Dashcams Collect
350,000+ AI-powered dashcams already on U.S. roads passively capture ground-level imagery as they drive through work zones. No special hardware deployment needed.
.avif)
AI Detects
Nexar’s AI analyzes imagery to identify and classify 8 types of work zone elements — from grabber cones to arrow boards to barriers. Each detection is GPS-tagged, time-stamped, and accompanied by photographic evidence.
Permit Cross-Reference
Detected work zones are cross-referenced against permit databases in real time. Overstays, early starts, and unpermitted activity are flagged automatically — with photo evidence attached.
.avif)
Map & Monitor
Detections are aggregated, geolocated, and displayed on an interactive map. DOTs can monitor all work zones across their jurisdiction, track changes over time, and export via API or WZDx-compliant feed.

Why CityStream
See Every Work Zone Without Leaving Your Desk
DOT staff currently send crews to physically drive through work zones to verify conditions. CityStream replaces manual compliance checks with continuous remote monitoring — dramatically reducing officer time on site visits and enabling proactive enforcement without adding inspection burden.
Know What’s Really Happening,Not What’s on the Permit
Detected work zones are automatically cross-referenced against permit data. The system flags overstays, early starts, and unpermitted activity — with photographic evidence. Ground truth, not paperwork.
The Freshest Road Datain the Industry
Highways refreshed in days. Arterials in about a month — roughly 50x faster than traditional survey cycles. 98% of U.S. main roads visited monthly. This isn’t once-a-year survey data. It’s continuous monitoringat scale.
WZDx Compliance, Out of the Box
CityStream outputs WZDx-compliant data natively — feeding accurate work zone data to mapping services, connected vehicles, 511 systems, and other agencies. 23+ state agencies already participate. Stay ahead of the federal standard with zero extra lift.
Revenue Recovery at Scale
Revenue Recovery at ScaleWork zone permit violations are a massive, largely untapped revenue source. NYC alone has $1.4B in uncollected enforcement fines. CityStream’s compliance layer identifies non-compliant and unpermitted work zones — opening a path to recover fees that currently go undetected. In the City of LA, the platform is funded through recovered compliance and violation fees. It pays for itself.
Reduce Congestion. Improve Traveler Information
Work zones cause 24% of all non-recurring U.S. traffic congestion. Greater permit compliance accountability reduces unnecessary lane closures. Real-time work zone updates feed directly into 511 systems and WZDx feeds — improving traveler information accuracy across the board.
No survey vehicles. No new infrastructure. Immediate insights.
Everything in CityStream is powered by the Nexar dashcam network — 350,000+ AI-powered cameras already on U.S. roads, capturing the world as it actually is

WZDx-compliant. Out of the box.
The Work Zone Data Exchange (WZDx) is the federal standard for sharing work zone information with vehicles, navigation systems, and other agencies. 23+ states already participate. CityStream Work Zones outputs WZDx-compliant feeds natively — no integration work, no custom build. As connected and autonomous vehicles become the norm, WZDx compliance will be critical infrastructure. You’re already ready.

No driver data. No vehicle tracking. No exceptions.
Nexar’s on-device AI automatically blurs faces and license plates before any image ever leaves the dashcam. Driver routes are never shared. Start and end points are stripped. All tracking IDs are ephemeral — no individual driver can be identified or traced. Zero personally identifiable information is present in any work zone data delivered to customers.

Your Teams Can't Be Everywhere. Now They Don't Have To Be.
Work zones are dynamic. Traditional oversight models are not.
By the time an issue is identified through an inspection, report, or complaint, theoperational moment may already be gone.

Know Your Roads as They Are, Not as They Were.
Nexar provides AI-powered road intelligence that detects work zone activity from alarge, continuously refreshed connected camera network covering the majority of U.S.roads.
Using machine learning models, Nexar identifies work zone elements such as cones,barriers, barricades, and signage, then maps them into structured, geolocated workzone records.
This is not just what was planned. It is visibility into what appears to be happening onthe road.
